CLOTHES-WEINGER.

Specification of Letters Patent No. 34,920, dated April 8, 1862.

To all whom it 'may concern.'

Be it known that I, DANIEL B. CLEMENT, of Milton, in the county ofNorfolk and State of Massachusetts, have invented certain new and usefulImprovements in Clothes-Tringing Machines, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification, in which-Figure l is a perspective view of the machine; Fig. 2, a longitudinalvertical section through the middle of the same.

The object of my present invention is to simplify the construction of aclothes wringing machine so that the cost of its manufacture may bereduced; and also, to so apply the spring which presses the rollstogether that the pressure may be equalized at both ends of the rollwhich rises and falls when clothes are passed between the rolls. Thatis, that if an article is passed between the rolls, which is thicker atone side, or toward one end of the rolls, than at the other, and one endof the roll is raised higher than the other, that the spring may stillpress equally at both ends of the roll; and my invention consists inapplying the power of a single spring to both ends of the roll, throughlevers pivoted to the frame of the machine and connected at their outerends by the spring.

Thatothers skilled in the art may understand and use my invention, Iwill proceed to describe the manner in which I have carried it out.

In the said drawings A is the frame of the machine, which is to besecured to the tub by clamps B which are attached to the trame A byscrews a, and are closed at their lower ends by screws operating in theframe and turned by hand levers Z). The lower roll C has its bearings inthe frame A and is revolved by the crank D. The upper roll E rest-s uponthe lower roll, and has an aXle z' which tits in a vertical slot in eachside of the frame A and is free to rise and fall. A

pair of levers G made of malleable iron or other suitable material arepivoted one on each side of the frame A at e; each of these levers beingso pivoted to the `frame that a shoulder 7' on the lever will bear onthe axle z' of the roll E. The upper ends Aoit these levers are drawntoward each other by an india rubber or other suitable spring H. It willbe seen that any pressure applied to the roll E to force it away fromthe roll C .will be communicated through the levers G to the spring H,and that the resistance of this spring will be applied equally to bothends of the roll E, although one end of it may be raised higher than theother.

Instead ot' the shoulder j of the levers G bearing immediately on thejournal i of the roll E I sometimes interpose a block or bearing overeach end of the journal, which blocks may be varied in size to producemore or less pressure on the roll E, instead ot changing the spring Hfor one of a dierent strength.

This wringing machine, constructed as above, will be found to operatebetter than any other with which I am acquainted. A piece of clothes orother article which is thicker' on one side, or toward one end of therolls than at the other, may be passed through, and be equally pressedthroughout its whole cross section, which would not be the case if theupper roll rose parallel to the lower one 0r if an independent springwere applied at each end of the roll, as in this case the spring at theend of the roll which was raised the highest .would be compressed themost, and would consequently apply the most pressure to the articlebeing passed through the rolls, at the side at which the article was thethickest, scarcely pressing at all where the article was thin.

That I claim as my invention and desire to secure by Letters Patent asan improvement in clothes wringing machines, is-

Applying the power of a single spring H to both ends of the roll Ethrough t-he levers G substantially as described.
